Knut Anders Hatlen updated DERBY-5358:
--------------------------------------
Attachment: volatile-v2.diff
Attaching an updated patch (volatile-v2.diff), which only touches the
TableDescriptor class. The new patch adds a javadoc comment that explains why
the field is declared volatile. It also removes an unused variable from the
getHeapConglomerateId() method.

> The conglomerate number 4,294,967,295 looks suspicious, as it's equal to
> 2^32-1. Perhaps it's hitting some internal limit on the number of
> conglomerates? The test case used the in-memory back-end.
